Abstract: Methods and systems for reconstructing individual spectra acquired from laser interrogation spots in a 2D array illuminating a particle are described. A particle is positioned in a 2D array that includes multiple laser interrogation spots. The laser interrogation spots of the particle are detected in the 2D array using a spectrometer. Multifocal spectral patterns are generated based on the laser interrogation spots, and an individual spectrum for each laser interrogation spot is reconstructed based on the plurality of multifocal spectral patterns.
